產(chǎn)品詳細介紹
A large quantity of tuna fish filet was obtained commercially in 2004 for use as an intercomparison material. It was deep-frozen, freeze-dried, and then ground and sieved. The material was homogenized by mixing in a stainless steel rotating drum for 15 days. After checking for the homogeneity of the sample material, aliquots of about 15 g were packed into cleaned amber borosilicate glass bottles with Teflon lined screw caps and sealed in plastic bags. Approximately 500 bottles were produced.
